196 ENGLISH BOTANY. 



spine-cells, and with rudimentary stipule-cells in one whorl, scarcely 

 projecting above the surface ; lower portion of the stem almost always 

 with the whorls of branchlets rudimentary, and full of starch-grains, 

 [bulbils] resembling white, stellately 5- to 7-lobed rings, surrounding 

 the stem. Branchlets 4 to 8 in a whorl, 1- to 3-celled, subobtuse, 

 apiculate, simple or with 1 or 2 1-celled bracts at the nodes, resembling 

 the terminal portion of the branchlet. " Nucules subglobose, 9-striate ; 

 coronula minute, conical, persistent ; globules solitary or 2 together." 

 (Groves, Journ. Bot. 1881, p. 2.) [When the globules are in pairs, 

 only one bract is developed, the second globule taking the place of 

 one of the bracts.] 



In deep water, very rare. In Filby Broad, 8 miles from Great 

 Yarmouth, growing in water 4 feet deep ; Hickling Broad, Somerton 

 Broad, Stalham Broad, and Hundred Stream, Potter Heigham, Norfolk. 

 South Devon. First found by Mr. Arthur Bennett, in September, 1880. 



England. Perennial. Summer, Autumn. 



A large plant, somewhat resembling Nitella translucens. Stem as 

 thick as a stocking-wire, and the branchlets 2 to 6 inches long, 

 [sometimes, and especially in the form called C. ulvoides, much stouter 

 than represented on Plate 1910]. Remarkable on account of the white 

 granular starlike bulbils on the lower part of the stem,* from which 

 mainly the plant is propagated, as it very seldom fruits, though Mr. 

 Bennett has found both the male and female plants in Filby Broad. 



I have not seen British specimens, nor any foreign specimens, with 

 either nucules or globules. 



Star-bearing Chara. 



Section III.— EU-CHARA, 



Internodes of the stem more or less opaque, [rarely pellucid,] with 

 [or rarely without] a covering of parallel cortical cells, and with 2 whorls 

 (rarely only 1 whorl) of stipule-cells at the base of each whorl of 

 branchlets. Globule placed below the nucule taking the place of one 

 of the bracts, [or borne on a separate plant from that which bears 

 nucules]. Nucule with a persistent crown of 5 conspicuous cells, which 

 are erect or spreading. 



[A. Stem and branchlets without cortical cells, stipule-cells in one 

 whorl. 



[* For an account of these arid the bulbils on other species of Chara, see A. Clavaud 

 in ' Bulletin de la Socie"te Botanique de France,' Vol. X. pp. 137-148, pi. iii.]
